IMPROVEMENT IN APPARATUS FoR CARBURETING GAS.

Speciiication forming part of Letters Patent No. 144,863, dated November 25, 18773; application filed November 11, 1873.

To all whom it may concern: Y Be it known that I, ALONZO W. PORTER, of the city, county, and State of New York, have invented a new and Improved Apparatus for Carbureting Gas, of which the following is a specification My invention relates to that class of machines for carbureting gas in which the gas is carbureted as it issues from the burner, or at the point of combustion, by means of an appai ratus so constructed and arranged, in connec- A tion with a gas-jet, as to supply the carbureting material in proper quantities, immediately at the point of combustion, by means of a wick proceeding from a proper receptacle to a point in front of the burner, through a curved wicktube, in such a manner that the iiame from the gas-jet will play across said wick at right angles to the same, substantially in the manner hereinafter set forth. My invention consists in certain improvements in the receptacle or reservoir for the hydrocarbon iiuid, by which said receptacle may be attached to the gasfixture, so that it may be readily removed for cleaning, filling, &c. My invention further consists in certain improvements in said receptacle or reservoir, by means of which any surplus oil or hydrocarbon which may be carried to the outside of the receptacle by the capillary action of the wick, or which may find its way there during lling or otherwise, may be returned; and, still further, to a new and improved device for supplying air to the gas-jet at the point of combustion, and regulating the amount of the same, as will be more fully hereinafter set forth. v The principal object of my invention is to provide a safe, cheap, and practicable apparatus for carbureting, whereby the heavy asv well as the light grades of hydrocarbons may be used, and mixtures of hydrocarbons of varying grades may be entirely consumed, and no loss from condensation or the failure of the heavier portions to be vaporized will result. This has been attempted heretofore by means similar to my present invention; but such attempts have failed, owing to faults which are entirely overcome in my apparatus.

In the common class of carbureters, the hydrocarbon is taken upl in the form of vapor by the gas, and then conveyed to the point of It is evident that in my apparatus all portions of the hydrocarbon--the heavy as well as the light-will be consumed, as the said hydrocarbon is carried bodily to the point of combustion, and there commingled and consumed along with the gas.

In the drawing, Figure 1 represents a view of my apparatus, looking down upon the top; Fig. 2, an elevation, part in section 5 Fig. 3, a view of the air-supplying apparatus detached from the burner, full size; and Fig. 4, a sec tional view ofthe screw-cap, showing the drip tube or trap. l

A represents a spherical reservoir or receptacle, having at its bottom a stud or projection, B, which ts into and is locked in a socket, O, formed at the angle of the tube D, which is secured to the gas-xture in place of the ordinary burner. rIhe stud B is so arranged in relation to the socket O that it may be readily attached and detached from the same, being secured by any convenient locking device. I prefer, however, and have shown, an ordinary bayonet-lock as the most convenient. The

the same firmly in place, at the same time al lowing it to be readily removed when desired. To the burner I secure an over-cap,7 E, which is adjustable over the same, and consists of a thimble, slotted in the end, and somewhat larger than the burner, so as to leave a space between its interior and the outside of the burner. Its object is to supply and mingle with the gas escaping from the burner a quantity of air to increase the combustion. The air is drawn in between said over-cap and the the flame from said burner will play across its upper end at or about a right angle to the same. Said tube is provided with a ratchet for adjusting the wick. The lower part of the screw-cap G forms a Well, K, from which descends a tube, L, into the receptacle A. Said tube is coiled or curved, as shown at l, forming a trap in same, which cuts oft' the connection between the interior of the receptacle A and the external atmosphere. The object of said well and tube is to retain any oil carried over by the wick to the receptacle, and prevent it from finding its way down the outside of the same, and defacing or soiling the same and Wasting the oil. The ange F forms a small annular chamber around the mouth of the receptacle, which communicates with the Well K by means of an aperture, f, or 'its equivalent, and serves to collect and return any overow of the liquid that may be occasioned by illing and replacing the cap, or by Working up through the screw-cap G. The wicktube is supplied with a iiat felt Wick, in preference to the ordinary cotton wicking, and the tube D is covered with some non-conducting material, such as Wood, paper-pulp, &c., to prevent heating the reservoir.

What I claim isl. The combination of the socket attachment and lock with the hinged or pivoted yoke for securing the receptacle to its place, substantially as and for the purpose set forth.

2. The well K in the lower part of the screw cap, in combination with the trap-tube, substantially as and for the purpose set forth.

3. The flange around the mouth of the reservoir, in combination with the Well and traptube, as herein described.

4. The over-cap, adjustable over the end of the burner, for the purpose of supplying air to the llame, substantially as herein set forth.
